BOTTLE-CAPPING TOOL.

My invention relates broadly to `tools and more particularly to the construction of a tool :lor cappinw and sealing bottles for the protection oi" liuid contents thereof.

Une ot the objects oit my invention is to provide a simpliiied construction oi copper throat 'for a bottle capping tool which may be produced inexpensively on a quantity production basis by unskilled labor.

Another object oit my invention is to provide a construction of bottle copper wherein means are provided toreliectively retaining a rubber cushion within the cappingthroat arranged at all times to readily reject the crown caps troni the capping throat after the capping` operation.

lilly invention will be more clearly`understood from the following.specification with reference to the accompanying drawings, in which: y

l-leretotore in the art bottle capping tools have included as one disadvantage in their construction the defect of the ready loss ot the interior Washer Within the bottle capping` threat. Vihen this Washer drops out ot' the bott-le capping' throat the bottle copper be# comes relatively ineffective in the sealing" of bottles in that/the crown caps tend to hang in the throat of the bottle capper and destroy the etlectiveness oif the tool for the succeeding` capping operations. By my invention l provide e bottle capl'iing tool in which a plurality oil2 spurs are formed on the interior walls oi the bottle capiiing` throat in such manner that the spurs serve to hold a resilient gasket in position at all times. The resilient gasket has the property of extruding the crown cap from the throat at the end oi' the capping operation enabling` the capping,`

throat to be readily rt ised by angular 1nove- W ment of the bottle copper lever in a position ready for a succeeding' operation. ln the manufacture ot the capper throat according to my invention l provide a movable vertical plunger which is normally resiliently held in its uppermostposition to receive and sup port a bottle copper throat with its resilient gasket therein directly over a hexagonally shaped cutting' die. A pressing die is provided which lou'ers upon the plunger in such manner that the capping throat is rigidly secured between the plunger an the pressing; die. lu this position the bottle copper throat is ready i'i'or a spur cutting` operation and any tendency et distorting` the bottle capper throat or meshing the same out oit' shape is eliminated. The pressing die then advances against the resistance ol the plunger carrying,l with it the bottle capperthroat and pressing the saine over the heXagJ'onally shaped cutting die which operates to cut the spurs on the interior Walls oit the bot-tlc copper throat. `The in ernal resilient gasket is thereby substantially'securedwithin the bottle copper throat against its displacement or loss. L/ftt the end of the spur cutting operation the movement of thepressing die is reversed and on the upper stroke the resilient mounting of the plunger is brought into use for iorcing` the copper throat from the hexagonally shaped die in amanner in which the copper throat may be readily removed from the tool, the tool beingl then ready ior a succeedingl operation. y

Reierring` to the drawings in detail, ret erence character I designates the base ot the bottle capping;` tool having a vertical stand ard 2 thereon provided `with an adjustingl rack 3 :it its upper extremity. A vertical slidable carriage 4. is provided havinga lever `5 pivotally mounted at 6 thereon.. The lever isprovided at one end with a toot-hed estension which engages the rech; i enabling` the a cylindrical upperA portion of relatively vsmall diameter' and a cylindrical lower por tion of'relatively large diameter connected by a substantially horizontal wall 11. The small cylindrical portion 9 is apertured as )represented at 12 enabling a securing bolt 14 to be passed therethrough to support the bottlecapper throat upon the vertical slidable carriage v4. Within the,V cylindrical portion 10 of the' capping throat I insert atresilient 'gasket 15, rounded on its upper edge at 16 and substantially right angled at its lower Yedge 17. The gasket 15 is centrally apertured at 18 to facilitate the insertion of the gasket Vwithin thecapping throat as will more fully appearhereinafter.

A series-of capping throats such as the capping` throat 8 are fed` successively upon a plunger 19 illustrated in Fig-7 disposed concentrically within adie 20 secured as'represented at21 to a base member 22. The plung- Ver 19 is reduced in cross section at its extremity 23 forming fanannular shoulder 24 at a distance from .the-endof the plunger substantially less than the height of the small cylindrical portion 9 of the capping throat 8. The diameter of the extremity 23 of the j plunger 19`is slightly less than the diameter of the small cylindrical portion 9 ofthe capping throatfenablingthe capping throat to seat `snugly upon the vextremity 23 of the plunger with the wall 11 resting on the annular shoulder 24 of theplunger 19. The lower 'edge of the skirt of the cylindrical port-ion V10 ofthe capping throat is flared outwardly as represented Vat 25. A pressing die 26 having a cylindrical borel 27 therein is interiorly f shaped asrepresented at 28 to correspond with the horizontal wall 11 and the cylindrical portion 10 and the outwardly flaredskirt l 25 ofthe capping` throat 8. The plunger 19 is provided with an annular boss 29 arranged tosnugly yseat within a vertical guide 30 in the basev 22. The lower portion 31 of the plunger 19 is centeredfthrough guide plate 32 supported as represented at 3 3 upon the lower portionfof the base 22. The plunger 19 is normally held-in itsuppermost position by Y resilient means 34 which in the construction shown isin the form of a rubber cushion.

The plunger 19 protrudes through the hexagonally shaped die 2O supporting thecapping throat substantially as shown in Fig. 7. The

top .of the hexagonally shaped die 2() is ground in a concavemanner represented at v so as topresent six sharp cutting points 36,V 37,387., 39, 40 and 41 which become effec- Vtive to cut and roll up the spurs 42, 43, 44, 45,

"46 and 47 on the interior Wall of the cylindrical portion 10V of the capping throat 8.

The spurs are each formed as represented in ',Fig. 4 by the action of the die 20 and the downward movement of the capping throat 8 thereagainst. The cutting point 36 of the die 20 is shown biting into the material of the capping throat S and rolling up the material cut therefrom to form a spur 42. The sx spurs thus formed cooperate to retain the gasket 15 within the capping throat 8. 'lhe spurs are each displaced upwardly from the walls of the cylindrical portion comprising the capper throat leaving a recess in the wali extending into the wall less than one-half the thickness thereof. The outside surface of the wall of the throat is not pierced by the cutting of the spurs and only the inner surface is subjected to the cutting process in the formation of the spurs.

In the quantity production operation of the cutting tool the capper throat 3 is pressed on the extremity 23 of the plunger 19 and the pressing die 26 lowers upon the capping throat. The rubber gasket 15 within the capping throat has its apertured portion 18 seating snugly upon the upper cylindrical portion of the plunger 19 immediately below the shoulder 24. The capper throat is advanced upon the hexagonal guide 2O and seats perfectly thereon for the spur cutting operation in a manner in which the throat is prevented from being mashed out of shape or distorted as the pressing die 26 continues to advance, pressing the capper throat downwardly upon the cutting points of the hexagonal guide 20, the spurs are cut and rolled up against the rubber gasket 15. On the upward stroke of the press the rubber gasket 15, by reason of its resilient properties, forces the throat up off of the die 20 and the opera tion is complete. The throat can then be readily removed from the plunger 19 and the operations repeated for successive capping throats which are successively fed upon the plunger. y It will be understood that any number of spurs maybe cut in the capping throat for insuring the retention of the rubber gasket therein. The spurs serve to secure the resilient gasket in such a position that it is effective to push the crown caps out of the capping throat after the crowning operation upon a bottle.

While I have described my invention in certain particular embodiments, I desire that it be understood that` modifications may be made and that I intend no limitations upon the invention other than those imposed by the scope ofthe appended claims.
